Ring smart lock features a manual crank for emergency power

Amazon-owned Ring is launching its debut smart lock, a device engineered to prevent users from being stranded due to power failure. Unlike many competitors that require external 9-volt batteries or USB connections to provide emergency power, this new hardware features a built-in manual charging mechanism. By rotating the thumb-turn dial a few times, users can generate sufficient electricity to trigger the mechanism and unlock their doors.

This innovation addresses a significant pain point in the home security market by removing the necessity for physical backup keys or specialized external charging tools. By integrating the power generation directly into the device's interface, Ring offers a more seamless user experience during unexpected battery depletion. The product is scheduled for a United States release in the near future.
